Mitsubishi Heavy Industries, Ltd. (MHI) has built numerous ROPAX ferries. With the
socioeconomic background around ROPAX ferry operators, such as fluctuating fuel oil prices and
domestic cargo logistics, the need for energy-saving ROPAX ferries with a high capability of
attracting customers and freight is increasing more than ever before. This paper describes MHI's
efforts on the development of energy-saving ROPAX ferries equipped with new propulsion plants,
highlighting the perspective of a reduction in fuel consumption.
